Hacking Amazon Echo Through Its Remote

July 18, 2015 by Will Sweatman 27 Comments

This one’s crazy… literally one electronic device is talking to another. In spoken English. And it works.

We’ve covered several hacks for the Amazon Echo, but some might be surprised to learn that there is another piece of interesting hardware that comes along with it – a remote control. Wire in a Raspberry Pi to it, and you’ve given yourself a way to automate control of the Echo without ever taking the Echo itself apart. [Gamaral] did just this and gave his Echo some significantly enhanced capabilities.

He started off by identifying the power rails of the remote. Then he wires in a 3.3v voltage regulator and uses a 100 ohm resistor as a voltage divider to bring it down to the 1.8 volt logic level used by the Echo remote. A single wire runs from the Raspi GPIO to one of the tactile switches on the controller.

For software, the Raspi is running RPi buildroot with Espeak and a cron scheduler compiled in. This allows him to send commands to the Echo which makes it say just about anything he wants. But any voice commands accepted by the Echo should work. If you want to go outside of those boundaries check out the method of spoofing WeMo devices we saw the other day.

Be sure to check out the [gamaral’s] entertaining video below to see the hack in action.

Smart Hat Puts Your Head In The Game

[Arvind] has dropped his hat in the game of head mounted displays. With Google Glass pushing $1,500, it’s only natural for hackers to make a cheaper alternative. [Avind’s] $80 version might not be pretty, but it gets the job done.

Using a Raspberry Pi loaded with speech recognition software, a webcam, 2.5 inch LCD display and a handful of other parts, [Arvind’s] hat mounted display allows him to view email, Google Maps, videos or just about anything he wants.

An aspheric loupe magnifier lens lets him see the display even though it sits around 5cm from his eye. No outside light is allowed in. Only the guts of the webcam were used to give him the video and microphone. We’ve seen other head mounted displays before, and this one adds to the growing collection. Be sure to check out [Arvinds] site for a tutorial on how to build your own, and catch a video of it in action after the break.

Create Your Own J.A.R.V.I.S. Using Jasper

April 9, 2014 by Nick Conn 79 Comments

Tony Stark’s J.A.R.V.I.S. needs no introduction. With [Shubhro’s] and [Charlie’s] recent release of Jasper, an always on voice-controlled development platform for the Raspberry Pi, you too can start making your own J.A.R.V.I.S..

Both [Shubhro] and [Charlie] are undergraduate students at Princeton University, and decided to make their voice-controlled project open-source (code is available on GitHub). Jasper is build on inexpensive off-the-shelf hardware, making it very simple to get started. All you really need is an internet connected Raspberry Pi with a microphone and speaker. Simply install Jasper, and get started using the built in functionality that allows you to interface with Spotify, Facebook, Gmail, knock knock jokes, and more. Be sure to check out the demo video after break!

With the easy to use developer API, you can integrate Jasper into any of your existing Raspberry Pi projects with little effort. We could see Jasper integrated with wireless microphones and speakers to enable advanced voice control from anywhere in your home. What a great project! Thanks to both [Shubhro] and [Charlie] for making this open-source.
